function(arg..., options)
Parameters

{*}:Arguments passed from the tag. After the helper name, any space separated keys, numbers or strings are passed as arguments.
The following template:
<p>{{madLib "Lebron James" verb 4}}</p>Rendered with
{ verb: "swept" }Will call a
madLibhelper with the following arguments.stache.addHelper( "madLib", function( subject, verb, number ) { // subject -> "Lebron James" // verb -> "swept" // number -> 4 } );Unlike helper simple helpers will always pass the actual value (instead of a compute).

hashobject of the maps passed to the helper
Returns
{String|function(HTMLElement)}:
The content to be inserted into the template.
Returning an element callback function
If a helper returns a function, that function is called back after the template has been rendered into DOM elements. This can be used to create mustache tags that have rich behavior.
If the helper is called within a tag like:
<ul {{sortable}}/>
The returned function is called with the <ul> element:
stache.addHelper( "sortable", function() {
return function( el ) {
$( el ).slider();
};
} );
If the helper is called between tags like:
<ul>{{items}}</ul>
The returned function is called with a temporary element. The
following helper would be called with a temporary <li> element:
stache.addHelper( "items", function() {
return function( li ) {
};
} );
The temporary element depends on the parent element. The default temporary element
is a <span> element.
